INDIANAPOLIS – One by one, running backs that could have possibly helped the Indianapolis Colts ended up elsewhere.

The Minnesota Vikings claimed Ben Tate, who was released by Cleveland earlier this week, on Wednesday. Then LeGarrette Blount, who was released Pittsburgh on Wednesday, signed with his former team, the New England Patriots, on Thursday.

So barring the Colts making a run at another free agent, Trent Richardson and Daniel “Boom” Herron will be the team’s two primary running backs the rest of the season. The Colts could also promote Zurlon Tipton off of the practice squad.

The Colts and Arizona both put a waiver claim, a source told ESPN NFL Insider Field Yates. The Vikings were awarded Tate because they have a worse record than the Colts and Cardinals.

There were questions about Blount’s attitude, especially after he left the field before Pittsburgh’s victory over Tennessee earlier this week because he was upset over the lack of carries he was getting.

Getting carries with the Colts wouldn’t have been a problem for Blount because Richardson and Ahmad Bradshaw, who is out for the rest of the season with a fractured fibula, basically split playing time. The issue with Blount, though, is that he’s not a third-down back.

Blount signing with the Patriots could end up hurting the Colts later if the two teams meet in the playoffs. So instead of worrying about one running back, the Colts may have to deal with Blount and Jonas Gray. Blount rushed for 166 yards against them in the playoffs last January and Gray gained 201 yards on the ground against them last weekend.
