A back injury forced Séamus Power to withdraw from the John Deere Classic.

The opening round for the Waterford golfer at TPC Deere Run began well with a birdie at the first and he picked up another shot on eight. However bogeys on 10 and 11 was the first sign that Power was struggling physically. A run of three double bogeys from 15 only compounded matters in spite of a par at the last.

After his round of 77, Power informed PGA Tour officials of his decision to withdraw.
