Colts sign Phillip Tanner, Jonathon Sharpe

The Indianapolis Colts' attempt to find a replacement for running back Vick Ballard (Achilles) on the roster continues.

The Colts signed former Dallas Cowboys running back Phillip Tanner and linebacker Jonathon Sharpe on Tuesday.

Tanner spent the past three seasons with the Cowboys, primarily on special teams. He has only 56 carries for 149 yards and two touchdowns in his career.

The Colts released running back Chris Rainey for violating team rules Monday.

Sharpe had 132 tackles, including 23.5 for a loss, 5.5 sacks and three interceptions, in two years at North Greenville University. He took part in the 2014 Super Regional Combine in Detroit.
