Tyrone veteran Joe McMahon continues to be part of Mickey Harte's squad despite reports that he had quit the squad.
McMahon himself had indicated that he was breaking away to concentrate on studies but he continues to work on a one-to-one basis with the county's new strength and conditioning coach Peter Donnelly.
Another veteran of previous All-Ireland successes, Dermot Carlin, also remains part of the extended squad and is training under Donnelly's supervision.
The two were included among a list of six in circulation who were thought to have departed the squad.
McMahon had played at centre-back in the McKenna Cup final against Cavan but was replaced by Mattie Donnelly at half-time. His club, Omagh St Enda's, had been involved in the latter stages of the Ulster championship.
Kyle Coney was the other high-profile player who departed the squad in advance of the league. Mark Donnelly and Plunkett were also released at the same time.
McMahon and Carlin are understood to have travelled to Castlebar for Tyrone's recent away Division 1 league win over Mayo.
The 31-year-old McMahon is studying in Coleraine and also has a young family but Harte clearly still values the versatility he can provide in a range of positions.
Tyrone responded well with victory in Castlebar after losing their opening match at home to Monaghan, having led by five points at one stage in the first half.
Allowing two veterans like McMahon and Carlin to work on their own programmes is in contrast to older players from other Ulster counties who have had to quit inter-county squads because they were not in a position to meet the demands being placed on them.
