Both teams have struggled this season behind young quarterbacks. The Jaguars enter the game with a 2-11 record. They've lost two in a row after pulling off a win over the Tennessee Titans. The Dolphins are 5-8 this season and sit in last place in the AFC East.
The Jaguars' biggest issue this season has been the unavoidable: injuries. Franchise running back Maurice Jones-Drew has been out since Week 7 against the Oakland Raiders with a foot injury.
The Dolphins have been more on the bad side than the unlucky side. Miami started the season 4-3 but have lost five of their last six games. Miami's lone win in that span came against the Seattle Seahawks, 24-21.
Chad Henne will face his old team on Sunday. Henne took over for Blaine Gabbert in Week 11. This season, Henne has completed 52 percent of his passes for 1,217 yards and eight touchdowns. He's thrown five interceptions.
Rookie Ryan Tannehill has had an up-and-down inaugural season with the 'Phins. He's completed 57 percent of his passes for 2,709 yards, eight touchdowns and 12 interceptions.
Sunday's game will air on CBS.
