"Peter has been integrated back into training this week following on from his half-time replacement against Leinster last Saturday," said a Munster statement.
"All protocol re return to play has been followed and Peter has progressed normally in this regard. However, due to the heavy schedule in the upcoming weeks, including Rabo, Heineken and possible international involvement, a decision to omit Peter has been made."
Edinburgh must turn the form table completely on its head when they face the former two-time European champions at Murrayfield. The Scottish outfit have won just one of their opening four league matches and lie rock-bottom of the Pro 12 while their Irish opponents lie second in the table.
Edinburgh have already lost once to the Red Army, who gained a 34-23 win on the first weekend of the new season last month. And head coach Alan Solomons, in his first season in charge, admits his side must do better than last year's season to forget as they lost all six pool games including two victories for Munster.
Solomons said: "The goal is to get Edinburgh back on track and earn respect from our opponents, supporters and the general rugby public. "We can only do that through performances and we want to perform in such a way that we earn respect. If we perform well then the results will come. That's important for us."
Edinburgh had a storming campaign in this competition two years ago when they reached the semi-finals only to lose out against Ulster, but pulled off a shock result by defeating Toulouse. And they will need to rediscover that form pretty quickly when Munster arrive in Scotland's capital city.
The twice-finalists warmed up for their trip to Edinburgh by securing bragging rights in the 19-15 league win over Leinster last weekend, inspired by Keith Earls' try.
