Offensive guard Todd Herremans was scheduled for a Friday visit with Grigson at the team complex. Herremans, 32, was recently released by the Eagles after starting 124 of 127 games in 10 seasons.
Grigson is the Eagles’ former director of player personnel and was a regional scout when the team drafted Herremans in the fourth round of the 2005 NFL Draft.
He knows Herremans, at 6-6 and 321, can play guard or tackle. That versatility could be beneficial for an O-line that has struggled to protect quarterback Andrew Luck, who has been sacked 100 times in his first three seasons.
Herremans has said he would like to play for a Super Bowl contender. The Colts have won 11 games in each of the past three seasons and advanced to the AFC title game last postseason.
The Colts have Anthony Castonzo at left tackle and Gosder Cherilus at right tackle, so Herremans would likely compete for playing time at guard if Grigson signs him after free agency begins Tuesday. Cherilus was effective in his first season with the Colts in 2013, but hampered by injuries in 2014 before being placed on injured reserve during the postseason.
Cherilus has three years remaining on his contract. Castonzo, a 2011 first-round draft choice, is the team’s best blocker and will be in a contract year.
Jack Mewhort, a 2014 second-round choice, showed promise as a rookie at left guard, but former third-round selection Hugh Thornton struggled at right guard in his second year before finishing last season on injured reserve.
Left guard Donald Thomas has played just two games since signing a four-year, $14-million contract with $3.5 million guaranteed in 2013. He was placed on injured reserve after tearing his right quadriceps in the second game of the 2013 season, then tore the muscle again during a training camp practice and was lost for the entire 2014 season.
Thomas would count $3.75 million against the cap in 2015, but the team could save $3.25 million if he were to be released before June 1.
The Colts signed former Canadian Football League guard Ben Heenan last month.
Guard/tackle Joe Reitz, a local product from Hamilton Southeastern High School, is set to become a free agent after playing in 44 games, including 24 starts, in the past four seasons with his hometown team.
