Lions reveal extension for Jim Caldwell; reportedly signed this summer

The Detroit Lions revealed they signed head coach Jim Caldwell to a contract extension Saturday, according to NFL Network's Ian Rapoport.

ESPN's Adam Schefter reported that Caldwell signed the extension months ago, but it was only publicly disclosed Saturday.

Terms of the deal were not disclosed by the club.

Caldwell is in his fourth season as the Lions' head coach, steering the team to playoff appearances in 2014 and 2016. The Lions are off to a 2-0 start under his tutelage and square off against the Atlanta Falcons on Sunday.

Detroit has posted a 29-21 cumulative record in Caldwell's tenure with the club.
