Rey Mysterio has been injury plagued over the last few years in the WWE, and with his contract expiring in about two months the "master of the 619's" WWE tenure could be coming to a close according to Wrestlingheadlines.com.

According to the report, the WWE has mixed feelings on Mysterio's deal running out. Mysterio is and oft-injured talent but his merchandise is one of the top sellers in the company.

The report indicates that with the end of Mysterio's contract in sight, it is typical of the WWE to aggressively pursue a new deal. But that isn't happening so far.

Mysterio was curiously booked in Northern California shows last weekend while another WWE show was going on in his home city of San Diego. The reason reportedly is because the WWE felt as though Mysterio is booked in San Diego way too often. Wrestlingheadlines.com reports that the San Diego attendance was the lowest of last weekend's shows.

Mysterio isn't the only talent that may be leaving soon, as Alberto Del Rio recently expressed frustration with his role in the company and hinted that he may leave when his contract expires, which should be shortly after Mysterio's.

According to a report earlier this month, Del Rio, a former WWE and World Heavyweight Champion, is frustrated over the fact that he used to be a main player in the WWE and is now just being used as fodder for Batista as a way to get the returning "Animal" over. Batista is expected to go over Del Rio at Sunday's Elimination Chamber event en route to main eventing WrestleMania XXX.

Perhaps no one was more frustrated with their standing in the company than CM Punk, who stormed out on the WWE prior to the Jan. 27 Monday Night RAW live show and hasn't been seen or heard from since. Punk was frustrated about part-timers main eventing WrestleMania as well as his role in the company.

Punk's deal was set to expire in July, but now it's doubtful that he'll return to see the deal come to a conclusion.

With Punk gone and Mysterio and Del Rio's deals expiring soon, the WWE could be without three solid talents come the summer time.
