The Undertaker's legendary WrestleMania streak will be defended once again this year, and though The Deadman, 48, hasn't appeared in a WWE ring since last April, he is expected to be back on Monday's edition of RAW. The Undertaker may be finally showing his age when he returns, as a recent picture has surfaced online of 'Taker sporting a gray goatee.

The Undertaker was photographed recently wearing a white goatee, but it's possible that he may dye it or shave it prior to his expected return on Monday Night RAW this coming Monday as the WWE plans on a huge episode to lead into the launch of the WWE Network that night.

The Undertaker was last seen during WrestleMania XXIX week last year. 'Taker disposed of CM Punk to extend his incredible undefeated streak to 21-0 at MetLife Stadium in New Jersey last year, and then made an appearance the next night on that week's slew of shows.

'Taker made his first RAW appearance in three years and teamed with Kane and Daniel Bryan in a losing effort against The Shield, then wrestled in his first SmackDown match that same week, defeating Dean Ambrose via submission before being powerbombed through a table by The Shield and once again disappearing from television.

'Taker will appear on RAW Monday as the WWE is expected to roll out many of their legends and old talents as a way to promote the launch of the WWE Network. Hulk Hogan is also rumored to be making his return to the company that night.

The Undertaker is expected to go to WrestleMania XXX on April 6 at the Mercedes-Benz Superdome to defend his undefeated streak and try to go 22-0 at the WWE's marquee event.

While there were rumors that The Undertaker would face Sting in a dream match at this year's event, it's looking more and more likely that 'Taker will be facing Brock Lesnar--who is also scheduled to appear at RAW on Monday--at WrestleMania XXX.

It remains to be seen what The Undertaker's plans are for the biggest show of the year, but after almost a year off, The Deadman will return to the WWE on Monday.
