They posted a poor first half showing, having gone behind early on but recovered sufficiently to earn a share of the spoils.
Rovers failed to deal with an early free-kick that was sent to the back-post and Connor O'Riordan bundled in after slipshod defending from the visitors.
Shortly after Rovers were indebted to goalkeeper Ted Sharman-Lowe after a terrific stop to deny Kane Hemmings' close-range header.
The rest of the half saw Grant McCann's men toil to no avail and another couple of smart saves from Sharman-Lowe ensured it was only a 1-0 deficit at the interval.
The second half didn't see a vast improvement and McCann made four substitutions at once, just after the hour mark. And not long after they finally drew level. A Luke Molyneux corner was met by a booming header from Owen Bailey to restore parity.
Crewe had the better of the chances to pinch all the points before Rovers saw a penalty appeal involving sub Joe Sbarra waved away.
Here's how we rated the Rovers players:
1. Ted Sharman-Lowe 6
Looked to dither for the opener. Redeemed himself after that though, with a terrific save to keep out Hemmings' header just after as well as other important blocks and stops throughout the second period. Photo: Andrew Roe/AHPIX LTD
2. Tom Nixon 5
A problematic afternoon down the right flank as he once again filled in at right-back. Hooked midway through the second half as one of four changes. Photo: Bruce Rollinson/AHPIX LTD
3. Richard Wood 6
First start in seven months for the skipper. Important moments where he calmed nerves and showed his nous. Photo: Howard Roe/ahpix.com
4. Tom Anderson 5
Some really clumsy moments which Crewe's nippy midifielders and forwards took advantage of. Did at least chip in with most number of clearances. Photo: Howard Roe/ahpix.com
