And a 50 ohm line on 0.062 FR4 needs a 2010!
Here's an 0805 terminating a 50r trace on 30 mil FR4

which is pretty good for a regular resistor. Two 100r resistors, in a y or tee shape, would be a little better.
And a TDR comparison of an 0805 mounted normally, and flipped over:

The capacitive bump at cm 1 is the SMA connector-PCB transition.
