The Irishman serves the final game of the two-match ban he received for picking up his 10th yellow card of the season against York.
Pilgrims boss John Sheridan will run the rule over on-loan Lee Cox ahead of kick off.
The midfielder, 22, has missed his side's last two games with the shoulder injury he sustained in the victory over Exeter on March 30 and is rated as doubtful.
Sheridan will also check on veteran midfielder Paul Wotton who was taken off in the second half of Saturday's 2-0 victory over Cheltenham, but could recover in time to play some part. Jamie Lowry and Warren Feeney remain sidelined.
Plymouth have won four of their last five games and currently sit 18th in the npower League Two table, just three points above the relegation zone.
