The Oklahoma City Thunder have agreed to a five-year deal worth nearly $25 million with restricted free-agent forward Kyle Singler, sources confirmed.

The final year of the agreement is a team option, sources said.

With Singler signed, the Thunder now turn their attention to finalizing an agreement with restricted free agent Enes Kanter. According to sources, the Thunder were set to meet with Kanter and his representation Wednesday and are said to be in a strong position to re-sign the Turkish big man.

Signing Singler also could spell the end for Perry Jones III and/or Steve Novak as the Thunder look to clear roster spots and shed additional salary as they move into the luxury tax.

Singler, 27, was selected by the Detroit Pistons 33rd overall in the 2011 draft, but traded to the Thunder at the deadline in February as part of a three-team deal. He appeared in 26 games for Oklahoma City, starting 18, after appearing in 54 (40 starts) for the Pistons.

With the Thunder, he averaged 3.7 points on just 33 percent shooting (37 percent from 3-point range) with 2.1 rebounds per game. That was a significant decline from his consistent production with the Pistons, where he averaged 7.1 points on 40 percent shooting (40.6 percent from 3) and 2.6 rebounds.

Singler didn't anticipate stepping into Kevin Durant's shoes, but was forced to once the former MVP was ruled out for the season due to injury. Singler was inconsistent in the role, struggling to find his shot, which eventually led to him dropping out of the starting lineup in late March and out of the rotation altogether in April.

Thunder general manager Sam Presti was on record saying he wanted to re-sign Singler.

In three seasons, Singler holds career averages of 8.1 points and 3.4 rebounds while shooting 37.8 percent from 3. A four-year player at Duke, Singler won a national championship in 2010 and was named the Final Four's most outstanding player.
