Tiger Woods abruptly withdrew from the Genesis Invitational at Torrey Pines on Monday, saying he was still processing the death of his mother. Kultida Woods died unexpectedly last Tuesday at the age of 80.

Tiger Woods has withdrawn from this week’s Genesis Invitational at Torrey Pines, saying he’s “just not ready” to do so. Monday’s announcement comes less than a week after his mother, Kultida, passed away. Woods did not give a cause for her death when he delivered the unfortunate news via social media on Feb. 4.

Woods, the tournament host of the Genesis Invitational, said he hoped to be at Torrey Pines later in the week and “appreciate the continued kindness since my Mom’s passing.”
