London Irish 33-33 Sale
Nick Macleod kicked a last-minute penalty to earn Sale what could be a vital draw and four-try bonus point against fellow strugglers London Irish.
Sale led at the break after tries from Henry Thomas, Mark Cueto and Kernan Myall cancelling out efforts from Guy Armitage and Halani Aulika.
Further tries from Sale's James Gaskell and Irish's Max Lahiff followed before Tom Homer and Macleod kicked penalties.
