Kiper's San Diego choice out of combine

The player Mel Kiper believes will end up being the San Diego Chargers’ first-round pick has reportedly withdrawn from the combine.

NFL.com reports that USC tackle Tyron Smith has dropped out of the combine suddenly Saturday with a lingering knee issue. He is going to save himself for his pro day workout in late March. He reportedly was injured eight weeks ago.

In Kiper’s latest mock draft, he penciled Smith in for San Diego at No. 18.

If Smith is the Chargers’ top target, this could change things some. The fact that Smith is going to work out before the draft still allows him to salvage his draft status. But this is a deep tackle group, and the Chargers could look at other tackle prospects Anthony Castonzo of Boston College, Nate Solder of Colorado and Gabe Carimi of Wisconsin.

San Diego will also look at several other positions in the first round, including linebacker, defensive end and receiver.
