The IRFU have confirmed that no appeal will be lodged with the Six Nations regarding the suspension of Brian O'Driscoll.
O'Driscoll was suspended for three weeks following a stamping incident during the RBS 6 Nations Championship game against Italy in Rome on March 16.
The 34-year-old will miss Leinster’s Amlin Challenge Cup quarter-final against Wasps on April 5 but his ban expires three days later, making him available for the latter stages of the RaboDirect PRO12 title push.
O'Driscoll, playing in what is thought to have been his 125th and final Test for Ireland, was sent to the sin-bin for only the second time in his 14-year professional career in the 22-15 loss at the Stadio Olimpico.
The 34-year-old lifted his right leg and brought it down on to the chest of Favaro, the Italy openside, who yelled out in pain.
