Ponte Vedra Beach, FL (My Sportsbook) - The grandfathered wedges and irons used by Phil Mickelson and others this season will no longer be allowed on the PGA Tour after the company that makes them agreed to waive its rights from a decades-old lawsuit.

The waiver, announced Monday, means Ping's controversial Eye2 clubs will no longer be exempted from the new PGA Tour regulations banning clubs with square grooves.

"We all believe it is in the best interests of golf," John Solheim, chairman and chief executive of Ping, said in a release

The waiver goes into effect March 29 and will apply to the PGA, Champions and Nationwide Tours. Following a request from the United States Golf Association, the waiver will also be applied to the U.S. Open.

"John Solheim and Ping had a terrific opportunity to do something very positive and significant for the game of golf and we very much appreciate his willingness to take this action," PGA Tour commissioner Tim Finchem.

Because of a 20-year-old settlement between Ping and the USGA, all EYE2 wedges made before April 1990 were exempted from the new rule that required players to switch to clubs with V-shaped grooves beginning this season.

The grooves regulation was implemented by the USGA to make it harder for players to control the ball out of the rough.

Mickelson carried an Eye2 wedge in his bag at Torrey Pines in January, prompting tour veteran Scott McCarron to accuse him of cheating. Other players, including John Daly, have also taken advantage of the loophole.

The waiver does not take all EYE2 irons and wedges out of competition. Clubs with grooves that conform to the new regulations will still be allowed. Ping said it has made EYE2 clubs with conforming grooves for several players.

Solheim said his company considered several solutions to the issue since meeting with USGA officials last month, but that waivers were the most appropriate way to honor the original competition agreements it had with the PGA Tour and USGA.

"The problem is solved on the PGA Tour and the integrity of the original agreements is unaffected," Solheim said, noting that the EYE2 clubs would still be allowed in amateur events played under USGA rules.

The USGA said it will conduct a forum later this year to discuss ways to improve the equipment rulemaking process.
