He told evertonfc.com: "It was not something we had planned. I spoke to Paul Jewell about Stubbsy on Wednesday afternoon - I spoke to Alan and he wanted to speak to them.
"He wants to play Stubbsy and that is great because he is 36 and sometimes you feel like hanging up your boots but not Stubbsy.
"I felt we had to go try and get some cover in so went and did some last minute shopping.
"We have a busy period coming towards the end of the season and we might need to use him. I could not take the chance of only having three centre-halves at the Club in case we had an injury or suspension. Hopefully he will be fit in the next couple of weeks."
