Jamie Roberts - or rather Dr. James Roberts - is a top ranked centre who plays (still) for Wales (67 caps), and has played for the British & Irish Lions. Apparently, he made a particularly effective tackle in the game against France on Saturday which Wales won.
In addition to being a professional rugby player, he continued his studies and graduated with his medical degree in 2013.
Google his name and you'll find a rich trove of pics. Here are some that I liked.
