SANTA CLARA, Calif. (AP) -San Francisco 49ers cornerback Nate Clements has undergone a CT scan on his broken right shoulder blade and left tackle Joe Staley had an MRI exam on his sprained right knee to further determine the damage.

Both players, injured during San Francisco's 18-14 loss at Indianapolis on Sunday, are expected to miss at least this Sunday's home game with the Tennessee Titans. They will probably miss the following game Thursday against Chicago as well considering the quick turnaround between contests.

Coach Mike Singletary said Monday that Clements wouldn't be placed on the season-ending injured reserve list and Staley said he didn't consider his knee injury to be season-ending.

In addition, defensive end Demetric Evans is nursing a sprained shoulder.
