Anyinsah was replaced by Ellis Harrison in the starting line-up for the 2-0 win over Port Vale and the youngster is likely to continue in the XI if the former Charlton winger's on-going problem rules him out.
Pirates boss John Ward is also hopeful that defender Mark McChrystal will be available again after he missed Tuesday night's victory with an ankle injury.
Danny Woodards replaced the loanee against Vale and the former MK Dons man could move back to the central midfield position he has made his own in recent weeks.
Rovers are now 11 points clear of the relegation zone thanks, in part, to their impressive home form. Ward's men have won six of their last eight matches at the Memorial Stadium.
