The good news for the 49ers: In regards to the four injuries they sustained Monday night, the might have “dodged some bullets” and none of those injuries are considered long-term, Jim Harbaugh said today.

The bad news, however, is that’s still no guarantee linebacker Patrick Willis (toe) and cornerback Jimmie Ward (quadriceps) will be available when they visit the Broncos on Sunday night.

Willis is dealing with a sprained left big toe – or “turf toe” – according to ProFootballTalk.com. On KNBR this morning, though, Harbaugh disagreed with that diagnosis, but didn’t offer specifics.

“He’s continuing to be evaluated,” Harbaugh said. “I don’t think it’s a long-term thing, so that’s a positive.”

If Willis can’t play, rookie Chris Borland, a third-round pick, will make his first career start Sunday night. In a 31-17 win at St. Louis on Monday, Borland entered late in the second quarter and had two tackles and two pass breakups, sharing team-high honors in the latter category.

Meanwhile, Harbaugh was relatively optimistic regarding Ward’s injury. In terms of severity, Harbaugh likened it to Willis’ injury and said it shouldn’t be a long-term issue.

If Ward is sidelined Sunday, Perrish Cox would likely move inside and play nickel corner, while rookie Dontae Johnson would take Cox’s spot on the outside.

If Willis and Ward can’t play, the 49ers will likely face Peyton Manning without two of their top three cornerbacks (Ward and Tramaine Brock) and three of their four starting linebackers (Willis, NaVorro Bowman, Aldon Smith).

In other injury news, left guard Mike Iupati (concussion) “looked really good” after the game, according to Harbaugh, but will have to go through the NFL’s concussion protocol this week to be cleared to play.

Wide receiver Stevie Johnson was sore Tuesday after he took a knee to his rear end while recovering an onsides kick, Harbaugh said. After the game, Johnson was optimistic he wouldn’t miss a game.
