The Detroit Lions have signed head coach Jim Caldwell to a multi-year contract extension. According to Ian Rapoport of NFL Network Insider, the signing happened this spring, but the Lions only reported it Saturday. The Lions did not disclose the length and the value of the contract. Caldwell assumed the position in 2014 and led the Lions to a 29-21 record through Week 2 of this season. In his three-plus seasons with the Lions, the team made it to the playoffs twice.

In his first season, Caldwell led the Lions to the playoffs with an 11-5 mark but missed the postseason the following year.

In 2016, the Lions made it to the playoffs again behind the outstanding performance from Matthew Stafford, who threw for 4,327 yards and 24 touchdowns with just ten interceptions.

Recently, the Lions made Stafford the highest-paid player in the NFL, signing him to a five-year deal worth $135 million. This season, Stafford has thrown for 414 yards, and six touchdowns with just one interception for a passer rating of 114.6 as the Lions improved to 2-0 with victories over the Arizona Cardinals and the New York Giants. They will face the defending NFC champion Atlanta Falcons in Week 3 Sunday.

Andrew Luck may return in Week 6

According to Rapoport, Indianapolis Colts quarterback Andrew Luck may start for the team in Week 6 when they take on the Tennessee Titans.

Rapoport said Luck may join practice this week as he prepares for his season debut. The Colts may not have to rush Luck with the way backup Jacoby Brissett played in their 31-28 win over the Cleveland Browns. Brissett completed 17 of 24 passes for 259 yards and a touchdown and ran for two scores as the Colts (1-2) notched their first win of the season.

T.Y. Hilton caught seven passes for 153 yards and a touchdown while Frank Gore carried the ball 25 times for 57 yards and a score for the Colts, who led by as many as 21 in the second quarter. Browns (0-3) rookie quarterback DeShone Kizer tossed an 11-yard touchdown pass to Kenny Britt and scored on a one-yard scoring run to trim the Colts' lead in the fourth.

Other injuries around the league

The Arizona Cardinals announced that wide receiver John Brown and left tackle D.J. Humphries will not play against the Dallas Cowboys Monday due to quad and knee injuries, respectively. The Cowboys will be down two cornerbacks when they take on the Cardinals with Nolan Carroll and Chidobe Awuzie out with concussion and hamstring injury, respectively.
