Lord Byron's tournament is moving a year earlier than expected.

Officials for the AT&T Byron Nelson and the PGA Tour announced Wednesday that the tournament will move in 2018 to Trinity Forest Golf Club, a course located about 10 miles south of downtown Dallas that opened for play this month.

The Nelson has been played at the Four Seasons Resort and Club since the TPC Las Colinas course opened there in 1983. The contract with the Four Seasons was for the tournament to stay there through 2018, but the last Nelson held in Irving, Texas, will be next May.

Trinity Forest is an 18-hole, links-style coursed designed by former PGA Tour player Ben Crenshaw and designer Bill Coore.

AT&T, the tournament's title sponsor, is based in Dallas.
