Not only are the top four linemen on IR, so too was the top reserve coming into the season. Tackle/guard John Wetzel has been on IR since Nov. 3 with a neck problem. Guard Jeremy Vujnovich (hamstring) is also on IR.

"It's a little different in the fact you have to grasp the offense so much faster, because we don't have the luxury of being here all year before being plugged in to play," Aboushi said of all the late-arriving pieces. "It's tough, but at the end of the day we are all professionals expected to go in there and perform. Whether that's extra meeting time with the coaches or spending more time in the playbook or asking more questions, whatever you have to do to be able to perform is what's expected. That comes with being in the NFL."

Barksdale was released after being a late scratch for personal reasons prior to the Chargers' Sunday night game against the Steelers. He was a former starter at right tackle who had been in a reserve role for Los Angeles, so he could be a potential answer at right tackle. Holden also has worked at guard, so there are myriad ways the Cardinals can reconstruct the line for the final month.

Odhiambo, a one-time 2016 third-round draft pick of Seattle, is the second offensive lineman the Cardinals have signed from the Indianapolis practice squad this season, following Zack Golditch. Odhiambo started seven games for Seattle in 2017 before a hand injury ended his season. Earlier this season, he was signed to the Falcons' active roster off the Colts' practice squad, before being released and going back to Indianapolis.

"Everyone does their part," said Cole, who as a rookie is the longest tenured member of the starting line. "Playing center, you carry a little bit more of the (leadership) role, but Oday has been in the league for six years, and even the guys who aren't in the starting lineup have done a good job leading this whole group and bringing everyone along."

BAKER, BUCANNON SIT OUT

With so many moves to injured reserve this week, the Cardinals' injury report shrunk. Safety Budda Baker (knee) and linebacker Deone Bucannon (chest) sat out Wednesday, as did wide receiver Larry Fitzgerald, who got his normal rest day. Defensive end Markus Golden (knee) was limited.

For the Lions, running back Kerryon Johnson (knee), linebacker Devon Kennard (hip) and linebacker Trevor Bates (ankle) did not practice. Defensive end Ezekiel Ansah (neck), fullback Nick Bellore (ankle), wide receiver Bruce Ellington (back), wide receiver Kenny Golliday (quadricep), wide receiver Brandon Powell (calf) and quarterback Matthew Stafford (back) were limited.
