Pittsburgh Steelers defensive end Brett Keisel (99) sits on the bench during the second half of an NFL football game against the Cleveland Browns in Pittsburgh, Sunday, Dec. 29, 2013. The Steelers won 20-7.

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.
