Indianapolis Colts general manager Ryan Grigson hails "magnificent" Jim Irsay

Indianapolis Colts general manager Ryan Grigson has lent support to team owner Jim Irsay following his arrest last week.

Irsay faces four felony counts of possession of a controlled substance having been arrested on suspicion of intoxicated driving late last Sunday.

The 54-year-old has since checked himself into a health-care facility, and Grigson revealed that the whole team was rooting for him to make a full recovery.

"Obviously nothing but great things to say about Jim, he's been magnificent and has done so much for myself, [coach] Chuck [Pagano], the entire building, everyone in the building loves the man," Grigson is quoted as saying by ESPN.

"We all would run through a brick wall for him. We all wish him a full, complete recovery and we're all pulling for him, and I'll leave it at that."

If convicted of the felony charges, Irsay could face a sentence of up to three years in prison on each count.
