Cowboys block Browns on Callahan

IRVING, Texas -- As top-heavy as the team's offensive staff may seem, the Dallas Cowboys do not want to part ways with Bill Callahan.

According to a source, Dallas turned down the Cleveland Browns' request to interview Callahan, the Cowboys' offensive coordinator/offensive line coach, who called plays in 2013 but will not call them in 2014.

Sources say the Cowboys have hired Scott Linehan, who will assume the play-calling duties. Callahan took over those duties from coach Jason Garrett in 2013, and Dallas averaged 27.4 points but finished 16th in the NFL in yards per game.

A source told ESPNDallas.com that Callahan, whose contract runs through 2014, would not be pleased with the addition of Linehan to the staff. A team can block a coach from interviewing with another team for any position other than head coach.

Callahan, who joined the Cowboys in 2012, worked with new Browns coach Mike Pettine with the New York Jets under Rex Ryan.

If the Cowboys allowed Callahan to leave, they could promote assistant offensive line coach Frank Pollack. He had more day-to-day contact with the line in 2013 because of Callahan's coordinator duties.

According to an NFL.com report, the team also turned down a request last week from the Baltimore Ravens.

The Cowboys have yet to announce Linehan's hiring, but he was involved in staff meetings Monday. He spent the past five years as the Detroit Lions' offensive coordinator.

In 2005, Linehan worked with Garrett on Nick Saban's staff with the Miami Dolphins.
