San Francisco 49ers linebacker Patrick Willis was scheduled to have an MRI on his injured groin on Tuesday. He injured his groin while running after Colts wide receiver Reggie Wayne in the third quarter last Sunday.
With the 49ers traveling to St. Louis to play against the Rams on Thursday night, Willis could be a game-time decision. The All-Pro linebacker has made 25 straight starts in the regular season and postseason. He has only missed a total of four games due to injuries in his six seasons in the NFL.
The Niners defense will already be without Aldon Smith, who is out indefinitely after being placed on the Reserve/NFI list. Should Willis not be able to play, Michael Wilhoite will likely start in his place for the first time in his career. The two-year veteran had one tackle after replacing Willis in the loss against the Colts.
At his press conference on Monday, Jim Harbaugh said tight end Vernon Davis continues to be evaluated. Davis injured his hamstring in Week 2 against the Seahawks and he missed last week’s game.
The tight end was at practice on Monday and Tuesday, however, he was limited. The Niners will offense will need Davis’ presence on the field if it wants to cure its aliments from the last two games. Otherwise, it will allow the Rams defense to focus in on Anquan Boldin even more, while forcing Colin Kaepernick to go to his other, less reliable receivers.
A new injury for the 49ers was to cornerback Nnamdi Asomugha, who injured his knee towards the end of Sunday’s game. The injury took place after Asomugha tried making a tackle on running back Ahmad Bradshaw. He also underwent an MRI and he did not practice on Monday or Tuesday.
