The Houston Texans have seen running backs drop like flies this year. They have already lost All-Pro back Arian Foster for the season, Ben Tate went on injured reserve for a rib injury, and now backups Dennis Johnson is banged up while Deji Karim is out for the year with a broken collarbone after Week 16.
Johnson suffered a hip injury and missed some practice this week, which speaks volumes for a player who needs as many reps as he can get. He was terrible against the Denver Broncos in Week 16, totaling just 29 rushing yards on 12 carries, so the questionable tag is more than legitimate.
Fantasy impact: The Titans are 29th in fantasy points allowed to running backs, so the matchup makes for an interesting scenario for fantasy owners. If Johnson sits, Grimes is actually a low-end RB2. If Johnson goes, this is a situation to avoid with too many variables.
