Max Woltman, Josh Andrews and Kyle Knoyle have all left Rovers so far.
Doncaster are now looking at wing-back options following Knoyle’s exit, but it is understood any arrival would likely be a loan signing.
The club is also hopeful of signing another player on loan this week.

The figures, revealed by the transfermarkt website claim Rovers’ squad is now worth £3.42m.
Here’s how that value ranks against their League Two rivals.
