Madigan and O'Byrne signed up
Munster hooker Kevin O'Byrne is the latest current squad member to be awarded a brand new contract, as has academy lock John Madigan this week.
UL Bohemians clubman, O'Byrne (24), has made one replacement appearance this term in the defeat away to Dragons at Rodney Parade.
O'Byrne captained the Munster U-18 Club side in 2008-'09 and won an All-Ireland in 2009 with the Highfield U-18s. He then went on to make his Pro12 debut when Munster lost 14-13 against Edinburgh in Thomond Park at the start of last season.
In his second season with the province, the Cork native, who featured in the Connacht academy, has played 12 times for the senior side, and is yet to play a game in Europe, as he continues his personal battle with the in-form Mike Sherry, Niall Scannell and the injured Duncan Casey for the coveted No 2 jersey.
O'Byrne was originally drafted into the squad when he impressed in the Ulster Bank League and Munster were struck by injury.
Greencore Academy prospect Madigan was part of Anthony Foley's plans in this and last pre-season, and he eventually made his Pro12 debut in the 18-13 win over Treviso at Irish Independent Park on September 5.
The 21-year-old Charleville native has played U-18s for Ireland also, but has had his game-time with Munster restricted due to injury.
He is yet another academy youngster that has graduated onto the senior side this year, following Rory Scannell, David Johnston and Sean McCarthy who have all been promoted recently.
