Former California wide receiver Keenan Allen, projected by many as a first-round pick, will not work out at this week's NFL Scouting Combine as he recovers from a knee injury, reports CBSSports.com's Bruce Feldman.

SI.com's Don Banks had the Dolphins selecting Allen 12th in his Mock Draft 1.0. NFL Network analyst Mike Mayock's has Allen second among wide receivers in his positional rankings.

But Allen has a Grade 2 PCL strain that his agent told Feldman should not require surgery. Allen - who missed three games with a PCL tear last season - will, as a result, not work out at the Combine and not run the 40-yard dash until the beginning of April. At Cal's pro day in March, he plans to run routes but not take part in any other drills.

If Allen can turn out a good 40 time in April and show he is healthy, his draft stock shouldn't be affected. But lingering concerns over the health of his knee could cause his stock to fall.
