Tennessee quarterback Vince Young will be day to day this week after reinjuring his right quadriceps muscle. His status for Sunday's AFC wild-card game with San Diego could be in question. "I can't really say right now if Vince is going to play this week," Coach Jeff Fisher said Monday. "I have a good feeling he'll be back on the practice field, and we'll see how he goes." Young missed a start Oct. 21 at Houston after straining his right quadriceps in Tampa on Oct. 14. He said he aggravated the muscle in the first half of Sunday night's 16-10 win at Indianapolis and tweaked it further in the third quarter.
