Australian Test vice-captain Travis Head returns between Sheffield Shield games to boost Tea Tree Gully, who will be at home against Adelaide, while Adelaide University regains left-arm swing bowler Nick Winter and opening bat Jake Weatherald for its clash with top side Kensington at Parkinson Oval.
The Browns will also benefit from the availability of opening bowlers Elliot Opie and David Grant. Opie was 12th man for South Australia in Brisbane this week while Grant played in the Futures League game in Perth.
Defending champions Tea Tree Gully will also welcome back young quick Tim Oakley - the leading First Grade wicket-taker - after making his Futures League debut.
Third-placed Adelaide is back in the finals for the first time in 12 years. Allrounder Cam Valente will be a key player, having scored 337 runs in four innings at an average of 168.5 and also taking 17 wickets. Ben Pengelley claimed career best figures of 7/36 to lead Adelaide to a win the last time these teams met in round six.
The games start at 10.30am.
