Titus Young (knee) did not practice Thursday.
Young's season-long knee tendonitis issues apparently aren't getting any better. Last week, he was able to put in three limited practices and earned a "probable" listing on the official injury report. This week, he's yet to even participate in practice. The Lions haven't expressed any real concern, but it's a situation to monitor. If active, the speedy Young has an enticing matchup with a Vikings secondary that has given up six touchdowns to Josh Freeman and Russell Wilson in the last two weeks.
