With one No. 1 overall draft pick at quarterback injured for the 49ers, the other No. 1 overall draft pick at quarterback won’t be getting the nod when the Niners host the Broncos in London.

Per multiple reports, the 49ers have given the starting job for Week Eight to Troy Smith.

Troy Smith was signed on September 6, after being cut by the Ravens. He gets the nod over David Carr, the first pick in 2002 who started five years with the Texans before bouncing around the NFL as a backup.

Carr completed five of 13 passes after Alex Smith injured his shoulder against the Panthers. Carr’s late-game interception helped send the 49ers to 1-6.

Alex Smith is expected to miss two-to-three weeks with a sprained shoulder.

Frankly, we’re not sure that Joe Montana in his prime would give this Niners team a good opportunity to win games.
