Facing the possibility that neither David Garrard nor Trent Edwards might be able to practice today, the Jaguars re-signed veteran quarterback Todd Bouman on Tuesday and are looking at the possibility of signing Patrick Ramsey.

UPDATE: Jaguars quarterback David Garrard not at team facility after suffering concussion

To make room for Bouman, the Jaguars cut veteran safety Gerald Alexander for the second time this year. If they sign Ramsey, they will have to cut another player.

Garrard was knocked out of the game in the second quarter of Monday night's 30-3 loss to Tennessee with a concussion after a hit by the Titans' Will Witherspoon, who had a free run at Garrard.

Jaguars coach Jack Del Rio said on Sirius NFL Radio that backup Edwards "has a little bit of a thumb issue that could be problematic."

"David's obviously not going to be working [today], and there's a question mark whether Trent will be able to go [today]," Del Rio said.

Del Rio did not hold a news conference Tuesday.

If Garrard and Edwards are sidelined, that would leave Bouman as the only healthy quarterback on the roster to work in today's practice as the Jaguars begin preparations for Sunday's game against the Kansas City Chiefs.

If Ramsey is signed, he would need time to learn the Jaguars' playbook.

Del Rio's comments indicate the Jaguars might not know until later in the week if Garrard can play.

There is no set formula for playing quarterbacks who have concussions, and physicians tend to be very cautious because players who suffer one concussion are more at risk of another one.

Whether they are allowed to play depends on the base-line tests all players are given and how long the symptoms, such as headaches, last.

Chicago quarterback Jay Cutler and Philadelphia quarterback Kevin Kolb both sat out a week after suffering concussions this season. Green Bay quarterback Aaron Rodgers played last Sunday after suffering a concussion the previous week.

Garrard is noted for his durability and is one of seven quarterbacks to start all 38 regular-season games since the start of the 2008 season. He was last sidelined in 2007, when he missed three games with an ankle injury.

Assuming that Edwards can play later in the week with the thumb injury, he appears to have a better chance of playing Sunday than Garrard.

Edwards, who was claimed by the Jaguars off waivers on Sept. 28, took a beating in his Jaguars debut and was in the training room a long time before he spoke to the media.

Garrard didn't meet with the media after the game.

About his physical condition after the game, Edwards said, "That's life of playing quarterback in this league that you do get bumps and bruises here, but I'll get back. I've been through this before. So I'll be able to recover and get back to work on Wednesday."

Bouman, who was out of football last year after being cut by the Jaguars at the end of training camp, was signed by the Jaguars on Sept. 21 after their original backup, Luke McCown, went down with a torn anterior cruciate ligament. He has since had surgery.

Bouman was cut Oct. 5 after Edwards had learned enough of the offense to play in an emergency. Bouman has the advantage of knowing the Jaguars system and could be a stopgap.

Ramsey was drafted in the first round by Washington in 2002. He has had stints with five other teams, including New Orleans. The Saints signed him in July but cut him Sept. 3 when he lost the backup job to Chase Daniel. Ramsey has a career 74.9 passer rating with 35 touchdowns and 30 interceptions.

Garrard and Edwards weren't effective against the Titans, and both weren't helped by wide receiver Tiquan Underwood, who apparently ran the wrong route on a Garrard interception. Del Rio said it was a miscommunication. Underwood also had a ball pulled away from him in the end zone on one of Edwards' two interceptions.

Garrard had a 33.0 passer rating. Edwards had a 40.3 rating.

The cutting of Alexander likely indicates that safety Sean Considine is ready to return after missing three games with a hamstring injury.

The Jaguars held Chris Johnson to 21 yards on 10 carries in the first half, but because the secondary was so shaky, the Titans held a 17-0 lead at halftime.

When Young was injured on the second series, backup Kerry Collins had no trouble throwing on the Jaguars. Young had a 142.5 rating, and Collins had a 108.9 rating.

Del Rio also said the officiating was a problem the Jaguars couldn't overcome against the Titans.

"When you add up the bad call, or questionable call in my mind on the pass interference, give me a break, it was almost laughable," Del Rio said. "[And] the face-mask [penalty]. I mean, David got hit in the head [with no call]. Maurice [Jones-Drew] got his face mask pulled at least two or three times, and we get some phantom call on our sideline. Those are things you have to fight through."
