Right-back Lynch proved his fitness in a 90-minute run-out for the Glovers' reserves in their 3-3 draw with Bristol City's second-string.
Yeovil are six points behind the Robins with four games to go following Monday's crucial 2-1 home win over relegation-haunted Leyton Orient.
Manager Russell Slade introduced Anthony Barry for former Bristol City striker Marcus Stewart, and on-loan Ipswich striker Darryl Knights for Lee Morris at half-time in that win.
The Glovers boss will now decide whether to stick with experience - Stewart and Morris - from the start at Ashton Gate or opt for youngsters Barry and Knights.
