Davis Riley, fighting to make the cut in the weather-delayed second round of the CJ Cup Byron Nelson, called a penalty on himself Saturday.

Riley self-reported that he used the slope feature on his distance-measuring device on the par-3 17th, his eighth hole of the round, which spilled over following a 6-hour weather suspension Friday.

Distance-measuring devices have been experimentally added to PGA Tour events since the Masters but use of the slope feature is not allowed.

Riley was assessed a two-stroke penalty and dropped from inside the projected cut line, at 5 under, to one back. He got on the number with a birdie at the next hole but gave it back with a bogey at No. 3, his 12th.

Riley is currently 89th in the FedExCup standings.
