 ## Avoiding Head-of-Line Blocking in HTTP/QUIC {#overview-hol-avoidance}
 
 Because QUIC does not guarantee order between data on different streams, a
 header block might reference an entry in the dynamic table that has not yet been
 received.
 
-Each header block contains a Largest Reference (see {{absolute-index}}) which
+Each header block contains a Largest Reference which
 identifies the table state necessary for decoding. If the greatest absolute
 index in the dynamic table is less than the value of the Largest Reference, the
 stream is considered "blocked."  While blocked, header field data should remain
