Former BYU defensive end Brett Keisel ended a busy day by going back to the NFL team he's always called home: the Pittsburgh Steelers.

According to ESPN NFL Insider Adam Schefter, Keisel agreed to re-sign with the Steelers on Tuesday, after reportedly declining an invite from the Cardinals to fly to Arizona for a physical earlier in the day.

Kent Somers of The Arizona Republic reported at 11:37 a.m. MDT that Keisel was flying to Arizona for a physical. The Cardinals were dealt a big blow Monday when defensive end Darnell Dockett was lost for the year with a torn ACL.

A second report, this one from NFL Network's Ian Rapoport at 1:59 p.m., indicated Keisel would unlikely sign with Arizona, however.

The reason why came from Somers almost an hour later.

Keisel has spent his entire 12-year career with Pittsburgh, winning two Super Bowls and making the Pro Bowl in 2010.

Keisel also has ties to second-year Arizona coach Bruce Arians, who served as an assistant coach with Pittsburgh from 2004-11. The former Cougar started 12 games for the Steelers last year and had 29 tackles and four sacks, but he will turn 36 next month.

Dockett, a third-round selection by Arizona in the 2004 draft, has been a reliable cog on the Cardinals' line over the past decade. The three-time Pro Bowler has started 156 career regular-season games (out of a possible 160) and missed just two games.

He tallied 4.5 sacks last season, his highest total since 2010. Dockett's play helped propel the Cardinals defense to a sixth overall NFL ranking in 2013.

In Pittsburgh, Keisel re-joins a Steelers defensive end rotation that includes projected starters Cameron Hayward and Cam Thomas, as well as rookie second-round draft pick Stephon Tuitt out of Notre Dame.
